Table 4 Fasting concentrations of plasma fatty acids and T max , C max , and Max∆C for each fatty acid following consumption of the test meal with algal oil or krill oil

From: Acute appearance of fatty acids in human plasma – a comparative study between polar-lipid rich oil from the microalgae Nannochloropsis oculata and krill oil in healthy young males
